SUMNER SHAV, OF BOSTON, MASSACHUSETTS.

COMBINED SHUTTER-FASTENER AND SHUTTER-BOWER.

SPECIFICATION forming part of Letters Patent No. 336,355, dated February16,1886.

(No model.)

To all whom it may concern:

Be it known that l, SUMNER SHAW', a citi` zen ofthe United States,residing at Boston, in the county of Suffolk and State ofMassachusetts,have invented an Improved Window- Blind Catch-Lock andBolt-Plate, of which the following is a specification.

My invention relates to that class of boltlocks and sill-plates designedto attach to window blinds and sills, and its object is to secure theformer to the latter at any angle and in such a manner as to impede therandom or unobstructed swing of the blind when the same is not closed.

My invention therefore consists in a springbolt or catch,aresisting-spring, andan actuatinglever or key,(the above aggregationcomprises the catch-lock,) which are severally arranged and securedwithin a suitable case or cover and vertically attached to the exteriorface of thelower or bottom frame of said blind in proximity to thehinged corner, beneath which is located the perforated receivingboltplate secured to the window ledge or sill, and which receives thebolt or catch and locks the blind when adjusted to any desired position.

Further improvements in detail will hereinY after be speciticallydescribed, and illustrated in the drawings forming a part of thisspeciication, in which- Figure l is an isometrical projection of aclosed window-blind and window-ledge bearing my improved catch-lock andbolt-plate, respectively. Fig. 2 illustrates in side elevation a blindopened and secured at right angles to the window, which, with theboltcase, is in vertical section. Fig. 3 exhibits a rear view of thelock in elevation, with the bolt depressed, and also dotted intodesignate the position of the actuating-lever and the bolt whenretracted. Fi g4 is a view in perspective of the actuating key or lever.Fig. 5 represents a modication of my invention, with the parts madeinterchangeable to permit the right and left use of the bolts in theirpractical application.

Like letters of reference designate similar parts in the various viewsthereof, referring to which- A indicates the blinds, and B theconnecting-hinges. C C are the lower or bottom frames ofthe blinds, andwhich receive and form the bed for said locks D, to which they arefirmly secured by screws E.

F indicates the bolt-plate, pierced with the concentric rectangularopenings G to receive said bolt, while the securing-screws are shown atH, confining said plate to the ledge or sill I ofthe window-frame J.

K, Fig. 3, indicates the flanges for the reception of the binding-screwsE. Y

L shows the depressed bed or chamber receiving the bolt lll. N and Odesignate the arms of said bolt projecting at right angles. The formerreceives the lower end of the resisting-spring P, while the lattersteadies and secures a uniform movement of said bolt.

Q exhibits the conoidal recess in the side of bolt, through which thesame is actuated by the key R, semi-rotated by the lever S. The movementofthe parts is indicated by the dotted lines, the swing of the leverbeing in the direction of the arrow.

T is the offset from the bed of the lock-case which, in connection withthe arm N of the bolt, previously described, forms the pocket for theresisting-spring l). Said spring holds the bolt firmly in a depressedposition, whence it enters into one of the rectangular spaces piercingthe bolt-plate F. Said spaces are so formed as to insure the entrance ofthe bolt end by compensating for the irregular distances the blind maybe hinged away from the window casing. These perforations should exceedin their length double the diameter of the bolt M, while their width isthe same, to insure close contact, and to avoid shitting or rattling ofthe blind.

Lugs U are cast upon the bottom of the bolt-plates to facilitate theirlevel adjustment upon the window-ledges.

In attaching my improved catch-lock to the exterior of window-blinds lpreviously mortise through the lower frame of the blind, at thedetermined point, to make an opening for the insertion of the key R.lVhen in a situation to operate the bolt, the lever or handle S assumesa vertical position next the window when the blinds are closed, andeasily accessible to the occupant, by whom the blind may be swung andlocked at any assumed angle by I DO releasing the rocker-handle S,permitting the bolt to drop into one of the rectangular openings in thebolt-plate.

The direction of the dotted lines, Fig. 3, indicate the manner ofwithdrawing the bolt i to release the blind.

In the modified construction of my improved invention, Fig. 5, theadditional features are duple segmental key-rests V V, a recess, W, inthe bolt, permitting the unimpeded vertical movement of the same, and aehamber,-X, in the head of said bolt to receive the resisting-spring P.Obviously the arrangement of these features permits the bolt M to beusedin a right or left hand position, While the absence of numerous partssimplies and renders my improved Windowblind eatehiook effectual andinexpensive.

Having described the operation and construction of my improvedinvention, what I 2o desire to secure by Letters Patent and claim 1s Inan organized shutter-fastening, the bolt M, and supporting-arms N O, therecess Q, and rocker-key R, operating in combination 25 with asill-plate, F, having lugs U, substantially as and for the purpose setforth.

In witness whereof I have signed this speci- -eatiou in presence of twoattesting witnesses.

SUMNER SHAW.
